Amen. I've worked in out of the printing publishing industry for about thirty years. Good pressmen have amazed me getting good print out of poor ink and lousy paper and quirky presses. I ran tests for a company developing a color printer ink jet in 1988. They had an issue with jams when wear started. We tried alcohol increasing the force onto the rollers, It required a redesign of the paper path. With the new path you could crumple the paper, flatten it, then feed it at 300 dpi. You could feed a piece of cloth through and get a decent print onto it. ___ gnhlug-discuss mailing list gnhlug-discuss@mail.gnhlug.org http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss/

Question about the ADF of a scanner.
I just scored a free HP C6270A scanner with an automatic document feeder. Sane seems to talk to it just fine. I'm *almost* happy. The ADF seems to jam up. Is there something that I personally can do that's cost effective to fix the ADF or am I SOOL? TIA -- Time flies like the wind. Fruit flies like a banana. Stranger things have .0. happened but none stranger than this. Does your driver's license say Organ ..0 Donor?Black holes are where God divided by zero. Listen to me! We are all- 000 individuals! What if this weren't a hypothetical question? steveo at syslang.net ___ gnhlug-discuss mailing list gnhlug-discuss@mail.gnhlug.org http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss/

Is there something that I personally can do that's cost effective to fix the ADF or am I SOOL? I have had this sort of problem with feed rollers on some scanners and printers. Basically, they get glazed and cannot pull the paper. Cleaning the feed rollers helps sometimes. Typically I use alcohol to clean them and then, if I'm still having a problem, a very, very mild abrasive (emery cloth, for example) to slightly roughen the roller surface. They are other cleaning supplies which used to help, but I don't know whether they still exist; they were used to clean typewriter rollers. Of course, there could be another cause, but this might help. ___ gnhlug-discuss mailing list gnhlug-discuss@mail.gnhlug.org http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss/
